ld: cannot open crt1.o

I'm trying to get my mipsel-linux environment to work, but no success:

% mipsel-linux-gcc test.c /usr/local/lib/gcc-lib/mipsel-linux/2.97/../../../../mipsel-linux/bin/ld:
cannot open crt1.o: No such file or directory
collect2: ld returned 1 exit status
Exit 1

% cat test.c

int main() {
        return 0;
}

% fgrep crt1.o -r /var/db/pkg/mipsel-linux-*
Exit 1

Here there's only the crt1.o from the base gcc (not the MIPS one):
% find /usr -type f -name crt1.o
/usr/lib/crt1.o

I feel like clearly missing something very basic here. Aren't these ports enough?

devel/mipsel-linux-binutils
devel/mipsel-linux-gcc
devel/mipsel-linux-kernel-headers

crt1.o is part of glibc; you only seem to have installed cross versions of binutils and gcc.
